The concept

Simply put, net metering is a process in which the electricity board keeps track of the energy consumed as well as generated by a solar-powered house. It allows consumers to feed surplus solar power into the state’s power grid when they don’t need it, and receive a credit on their electricity bill.

For example, if you live in a state that has implemented the net metering policy, then you get credited for the electricity you deliver back to the grid at the same retail price that you pay for the electricity you take from the grid.

Benefits

Needs less resources

Since net metering solar systems are installed on the roofs of residential houses and commercial buildings, they do not require large tracts of land like their large solar park cousins.

Also, as they use the state-owned power grid as a giant battery, they don’t require expensive battery backups to balance out the power consumption through the day. These reduce the expenditure on installation.

Improved energy utilisation

Power travelling from the grid to your home incurs significant transmission and distribution losses, thus wasting electricity generated by burning fossil fuels. These losses are almost nil in net metering systems as energy is generated and consumed at the same location.

This not only reduces energy congestion and stress on overall grid infrastructure more efficient, it also provides financial relief to the distribution companies (DISCOMs) and improved grid voltage to consumers.

Reduction in power bill

With net metering systems, you only pay for the deficit power consumed i.e. the difference between the power consumed by the household from the grid and the solar power generated from the panels. This drastically reduces your electricity bill while giving you an opportunity to earn an income.

Low maintenance

Net metering system components like solar panels, inverter and mounting structures need low to no maintenance. Since these installations do not require generators or batteries, considerable expense for their maintenance is avoided. This saves not just your money but your time too.

Lower per capita energy footprint

Deploying net metering systems also incentivizes the adoption of localized power generation through renewable technologies. this helps cut down the country’s per capita energy footprint.

How it works

In a rooftop net metering system, the DC power generated from the solar panels is converted to AC power using a power conditioning unit and is fed to the grid (the phase lines are selected depending on the capacity of the installed system and the regulatory framework specified by respective States).

These systems generate power during the day time, which is utilized fully to power captive loads and feed excess power to the grid. In case solar power is insufficient due to cloud cover or rain, the captive loads are served by drawing power from the grid.

To enable this system of net-metering, state electricity boards replace the existing service connection meter with a bidirectional meter that displays the import and export energy separately.

Saving

If we put our money in FD we will get 6.75% taxable income in a nationalized bank, but if we invest it in solar the ROI is assured 20-22%, with a payback period of 3-4 years and free power for 20 years.

Housing society spent almost 40 to 50 % on Light bill by doing net metering society will able to restrict the operation maintenance fee.

Rooftop solar

If you are considering renewable energy to cut down electricity bills or to do your bit for the environment, a rooftop solar solution is the answer to your needs. If your existing business premise has ample space to install rooftop solar, we offer you customized solar power solutions as per your needs to help you realize your business goals

Installing a rooftop solar power plant will substantially bring down your energy costs since solar tariffs are lower than prevailing grid tariffs. Moreover, it helps you to monetize your existing area, like rooftops or parking area, by enhancing its value. So, are you ready to make the switch?

Is your business ready to go solar?

Before you commission Sunirmiti Solar to design and install a rooftop solar plant installation, you must first evaluate the feasibility for setting up a rooftop solar plant on your existing roof.

We offer you turnkey solar solutions, right from designing and installation to maintenance, leaving you free to focus on your core business. All that is required is access to your unused roofs, and we’ll do the rest. However, before you commission a rooftop solar power plant, there are a few feasibility checks that you need to carry out. You can conduct these yourself, or we can send our expert to check.

Shadows: Is the rooftop free from large obstructions and the resulting shadows? Ensure there are no large trees, buildings or billboards that can hamper the path of direct sunlight. Dust: Is the area free from dust, pigmentation, haze or particulate matter? Is the site easily accessible for periodic cleaning and maintenance? Load-carrying capacity: Check the load-carrying capacity of the roof before installation. You might need to bolster the roof to take on the weight of the heavy technology used.

Engineers at Sunirmiti Green energy solutions will evaluate the location of your onsite solar system installation thoroughly before recommending a customized solution. We will come up with an innovative solution that will fulfil your requirements while meeting safety and regulatory compliances.

Whether you are looking to install ground mount solar or rooftop solar solutions in India, Sunirmiti green energy solutions is one of the leading solar developers in pune. At Sunirmiti, we are committed to offering you the best onsite solar system solution for your needs.

Frequently asked questions

Area required?

1 kWp solar system requires approximately 10 sq. m (or 100 sq. ft) of shadow free area. Therefore, one 1 MWp (1000 kWp) solar system would require 10,000 sq. m / 1,00,000 sq. ft / 3 acres of shadow free area.

Solar panel mounting?

Solar panels will be mounted on high-quality aluminum structures, which will be fixed onto the roof sheets.

Is it possible to mount the panels without drilling the holes in the slab?

Yes, if the roof sheets belong to the standing seam segment, then solar panels can be installed without penetrating the roof. If not, then penetration is necessary, although precautions are taken to prevent leakage by using proper washers and bolts. Installation on RCC roofs does not require any penetration.

How much is the subsidy available?

40% upto 3kW systems on the government base cost.
20% for above 3kW systems on the government base cost.
